Conventionally, as a board-mounted connector, a terminal is press-fitted into a press-fit hole provided in a housing, and one end of the terminal is used as a contact point (so-called tab) with a mating terminal, and the other terminal is used as a contact point (so-called tab). A connector has been proposed in which the end portion is used as a point of contact with a conductor pattern on a circuit board (see, for example, Patent Document 1).

JP 2020-187953 A

By the way, in a board-mounted connector, generally, a plurality of terminals are press-fitted into a plurality of press-fitting holes provided in a housing, and each of the plurality of terminals is arranged so as to electrically connect a mating terminal with a conductor pattern on a circuit board. It has become. In some cases, a large number of terminals are densely arranged in a small housing due to the demand for smaller size and lower height of the connector. On the other hand, excessively reducing the distance between adjacent terminals (so-called insulation distance) is not preferable from the viewpoint of achieving sufficient insulation between the terminals. As described above, it is generally difficult to achieve both miniaturization and low profile of a connector and maintenance of insulation between a plurality of terminals.

One of the objects of the present invention is a board-mounted connector capable of both reducing the size and height of the connector and maintaining insulation between a plurality of terminals, and a board with a connector using the connector. is the offer of

In order to achieve the above object, a board-mounted connector and a board with a connector according to the present invention are characterized by the following [1] to [5].

[4]
In the connector described in [3] above,
The second terminal portion is
a standing portion extending from the first terminal portion and extending along the intersecting direction through the curved portion; a first portion extending from an end portion of the standing portion in a direction along the axis; and the first portion. a second point extending toward the second contact point from the end of
It must be a board-mounted connector.
[5]
A board with a connector, comprising: a circuit board; and the connector according to any one of [1] to [4] mounted on the circuit board,
The circuit board is
The side edge of the circuit board has a notch recessed in a concave shape along the board surface,
The connector is
The housing is arranged to fit into the notch portion, and the second terminal portion of the terminal is conductively connected to the conductor pattern of the circuit board, and mounted on the circuit board.
It must be a board with a connector.

According to the board-mounted connector having the configuration [1] above, the housing has a plurality of first press-fit holes and a plurality of second press-fit holes provided in the housing. A partition wall is provided that protrudes and extends along the arrangement direction. Therefore, the insulation distance (especially creepage distance) between the terminals press-fitted into the first press-fitting hole and the second press-fitting hole can be increased compared to the case where there is no partition wall. Furthermore, since the partition wall has a shape extending along the arrangement direction, the plurality of first press-fit holes and the plurality of second press-fit holes can be collectively separated. Therefore, compared to the case where a plurality of independent wall portions are provided between each first press-fitting hole and each second press-fitting hole, when molding the housing with a mold or the like, it is possible to easily mold a thin partition wall portion. It is possible. In this manner, the partition wall can increase the insulation distance between the terminals, and can also reduce the thickness of the partition wall itself. Therefore, the board-mounted connector of this configuration can achieve both miniaturization and low profile of the connector and maintenance of insulation between a plurality of terminals.

According to the board-mounted connector having the configuration [2], the housing is further provided with an auxiliary wall portion projecting from the partition wall portion in the direction of the terminal row. By supporting the partition wall with the auxiliary wall, unintended deformation (for example, collapse) of the partition wall is suppressed even if the thickness of the partition wall is reduced. By arranging the auxiliary wall portion between the adjacent first press-fitting holes, it is possible to increase the insulation distance between the terminals press-fitted into the first press-fitting holes. The same applies to the case where the auxiliary wall portion is arranged between the adjacent second press-fit holes.

According to the board-mounted connector having the configuration [3] above, the second terminal portion having the second contact point to be conductively connected to the conductor pattern of the circuit board is conductively connected to the mating terminal. and has a curved portion extending from the first terminal portion having a first contact point that is curved about a curved axis along the axis of the first terminal portion. The terminal has a shape in which a first point of contact with the mating terminal and a second point of contact with the conductor pattern of the circuit board are offset. For example, if the terminal has a typical crank shape, after stamping a sheet metal into a preform having a first terminal portion and a second terminal portion (see, for example, the chain terminal shown in FIG. 8), One bending process may be performed at the above-described curved portion so that the first contact portion and the second contact portion are offset in a predetermined direction. In other words, the number of bending operations to be applied to the terminal can be reduced as compared with the number of times (at least two times) in the case of simply forming the terminal into a crank shape. If the terminal has a more complicated shape, for example, a preform having such a shape may be manufactured in the stamping stage, or an additional bending process may be performed after the bending process into the crank shape described above. may In either case, the number of times of bending can be reduced in the same manner as described above.

According to the board-mounted connector having the above configuration [4], the second terminal portion of the terminal extends from the first terminal portion and extends along the intersecting direction through the curved portion; and a second point extending from the end of the first point toward the second contact point. As a result, for example, even when the circuit board is arranged at a position offset in the cross direction from the first terminal portion (see, for example, FIG. 4), the number of times of bending during manufacturing of the terminal can be reduced as described above. , the terminals can be connected to the conductor traces of the circuit board.

According to the board with a connector having the above configuration [5], the terminal press-fitted into the housing is arranged such that the housing of the connector is fitted into the recessed notch of the circuit board. connected to As a result, compared to the case where the connector is mounted on the board surface of the circuit board, the height of the board with the connector can be reduced as a whole.

As described above, according to the present invention, there is provided a board-mounted connector capable of achieving both miniaturization and low profile of the connector and maintenance of insulation between a plurality of terminals, and a connector using the connector. I can provide the substrate.

The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading the following detailed description of the invention (hereinafter referred to as "embodiment") with reference to the accompanying drawings. .

<Embodiment>
A board-mounted connector 1 and a board 7 with a connector according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a connector 1 includes a housing 2 and a plurality of terminals 3 press-fitted into the housing 2, and is mounted on a circuit board 4 for use. By this mounting, the connector-equipped board 7 is manufactured.

Hereinafter, for convenience of explanation, as shown in FIGS. and "below". The "front-rear direction", the "left-right direction" and the "up-down direction" are orthogonal to each other. The front-to-rear direction corresponds to the direction in which the connector 1 and the mating connector (not shown) are mated. is the rear side. The horizontal direction coincides with the arrangement direction in which a plurality of upper press-fit holes 33A and a plurality of lower press-fit holes 33B (see FIG. 5 etc.) of the housing 2 are arranged. Each member constituting the connector 1 will be described in order below.

First, the terminal 3 will be explained. As shown in FIG. 5 and the like, the connector 1 includes a plurality of terminals 3, as shown in FIG. a terminal 3B; First, the upper terminal 3A will be described below.

The upper terminal 3A shown in FIG. 6 has curved portions 17, 20, and 22 (see 6) are respectively bent. The preform 3g includes a linearly extending first terminal portion 11 and a substantially L-shaped second terminal portion 12. As shown in FIG. Each of the first terminal portion 11 and the second terminal portion 12 has a rectangular cross section perpendicular to the extending direction.

As shown in FIG. 6, the first terminal portion 11 as a whole has a shape extending linearly in the front-rear direction. A front end portion of the first terminal portion 11 functions as a first contact portion 13 that contacts and is conductively connected to a mating terminal (female terminal, not shown) housed in the mating connector. A pair of press-fitting projections 14 that protrude in both left and right directions are provided at two locations in the front-rear direction on the rear side of the first contact point 13 of the first terminal portion 11 .

At a position behind the press-fitting protrusions 14 of the first terminal portion 11 , a wide portion 15 is provided that protrudes further in both left and right directions than the pair of press-fitting protrusions 14 . The wide portion 15 functions as a stopper that defines the longitudinal position of the upper terminal 3A with respect to the housing 2 when the upper terminal 3A is press-fitted. A rear end surface (rectangular plane orthogonal to the front-rear direction) of the first terminal portion 11 functions as a pressing surface 16 for pressing a press-fitting jig (not shown) when press-fitting the upper terminal 3A. For this reason, the press-fitting jig can be pressed against the pressing surface 16 positioned on the extension of the axis of the first contact point 13 , so that a dedicated pressing surface (for example, a so-called shoulder portion) is separately provided on the terminal 3 . The structure of the terminal 3 can be simplified as compared with the case where it is provided. Further, problems such as buckling are less likely to occur in the first terminal portion 11 during press-fitting.

As shown in FIG. 6, the second terminal portion 12 extends rightward from the rear end portion of the first terminal portion 11 (portion behind the wide portion 15) and curves upward at a curved portion 17. a standing portion 18 extending upward from the upper end portion of the curved portion 17; a first portion 19 extending rearward from the upper end portion of the standing portion 18; A curved portion 20 that extends toward and curves downward, a second portion 21 that extends downward from the lower end of the curved portion 20, and a lower end of the second portion 21 that extends downward. It also includes a curved portion 22 that curves rearward, and a second contact portion 23 that extends rearward from the rear end portion of the curved portion 22 . The second contact point 23 is conductively connected to the conductor pattern 42A of the circuit board 4 (see FIGS. 4 and 5). The curved portion 17 is curved around a curved axis X that is parallel and offset to the right from the axis of the first terminal portion 11 .

Thus, in the upper terminal 3A, the second terminal portion 12 is offset to the right with respect to the first terminal portion 11 (see FIG. 6A). Also, the second contact point 23 is offset downward with respect to the first contact point 13 (see FIG. 6(b)).

In the upper terminal 3A, a crank shape (see FIG. 6(b)) composed of the first terminal portion 11, the standing portion 18, and the first portion 19 as viewed in the left-right direction is bent once with respect to the curved portion 17. It can be obtained by bending. Therefore, the number of bending processes to be performed on the terminal to obtain the crank shape can be reduced compared to a general processing method in which the terminal is curved at two points in the extending direction to obtain the crank shape.

In the upper terminal 3A, the plate thickness T2 of the second terminal portion 12 (see FIG. 6A) is smaller than the plate thickness T1 of the first terminal portion 11 (see FIG. 6B) (see FIG. 8 ( b)). More specifically, the second terminal portion 12 is arranged such that the curved outer surface (lower surface in FIG. 8B) at the curved portion 17 approaches the curved inner surface (upper surface in FIG. 8B). The thickness T2 of the second terminal portion 12 is thinner than the thickness T1 of the first terminal portion 11 due to the reduced thickness shape. Therefore, the bending process for providing the curved portion 17 of the second terminal portion 12 is facilitated. Furthermore, in this example, the plurality of upper terminals 3A are arranged in the housing 2 in a state of being aligned in the left-right direction (see FIG. 4, etc.). In this case, among the upper terminals 3A adjacent to each other in the left-right direction, the curved portion 17 of the upper terminal 3A on the left side and the left end surface of the rear end portion of the first terminal portion 11 of the upper terminal 3A on the right side are the most in the left-right direction. approach (see FIG. 9(b)). In this regard, the plate thickness T2 (that is, the thickness in the left-right direction) of the curved portion 17 (=a part of the second terminal portion 12) becomes thinner in the direction away from the adjacent first terminal portion 11. As a result, the horizontal interval Y (so-called insulation distance) between the two can be increased.

In the upper terminal 3A, the width T3 (see FIG. 6B) of the curved portion 17 and the standing portion 18 in the front-rear direction is larger than the plate thickness T1 and the plate thickness T2. Therefore, the rigidity of the curved portion 17 can be increased, and the shape of the upper terminal 3A after bending the curved portion 17 is properly maintained. As a result, the coplanarity (flatness) of the second contact points 23 of the plurality of upper terminals 3</b>A is enhanced, thereby improving the reliability of the electrical connection between the circuit board 4 and the connector 1 . The upper terminal 3A has been described above.

The upper terminal 3A described above is manufactured, for example, as follows. First, a thin metal plate is punched to obtain a chain terminal in which a plurality of preforms 3g are connected by a carrier 5, as shown in FIG. 8(a). Next, for the series terminal, only the second terminal portion 12 of each preformed body 3g is press-worked in order, and the plate thickness T2 of the second terminal portion 12 of each preformed body 3g is reduced to that of the first terminal portion 11. It is made smaller than the plate thickness T1 (see also FIG. 8(b)). Next, in the chain terminal, the carrier 5 is removed to separate the plurality of preforms 3g, and the curved portions 17, 20, 22 (see FIG. 6) of each preform 3g are bent. Thereby, a plurality of upper terminals 3A are obtained. Part or all of the curved portions 17, 20, and 22 (see FIG. 6) may be bent before or after the upper terminal 3A is press-fitted into the housing 2. .

As can be understood from the manufacturing procedure described above, at the second contact point 23 of the upper terminal 3A, the punched surfaces (cut surfaces) produced when the thin metal plate is punched face the conductor patterns 42A and 42B of the circuit board 4. will be connected. From the viewpoint of achieving good electrical connection, in this example, the punched surface of the second contact point 23 is plated. Examples of plating materials include gold (Au). In addition, gold plating is generally provided on the underplating after providing underplating of copper, nickel, or the like on the base material. The same plating process may be applied not only to the punched surface of the second contact point 23 but also to the entire punched surface of the upper terminal 3A. In this example, a second contact portion 23 of a lower terminal 3B, which will be described later, is also plated in the same manner.

Next, the lower terminal 3B will be described. Regarding the lower terminal 3B shown in FIG. 7, the same or equivalent configuration as that of the upper terminal 3A shown in FIG. The second contact point 23 of the lower terminal 3B is conductively connected to the conductor pattern 42B of the circuit board 4 (see FIGS. 4 and 5). The lower terminal 3B is also manufactured from the chain terminal as shown in FIG. 8 through the same process as the upper terminal 3A. The lower terminals 3B also have the same actions and effects as the above-described various actions and effects of the upper terminals 3A. Main differences between the lower terminal 3B and the upper terminal 3A will be described below.

Contrary to the upper terminal 3A, the lower terminal 3B has a curved portion 17 extending leftward from the rear end of the first terminal portion 11 (see FIG. 7A). That is, the curved portion 17 is curved around the curved axis X that is parallel and offset leftward from the axis of the first terminal portion 11 . Therefore, in the upper terminal 3A, the second terminal portion 12 is offset to the right with respect to the first terminal portion 11 (see FIG. 6A), whereas in the lower terminal 3B, the second terminal portion 12 is offset to the left with respect to the first terminal portion 11 (see FIG. 7(a)).

In the lower terminal 3B, the overall shape of the second terminal portion 12 is different from that of the upper terminal 3A. Therefore, in the upper terminal 3A, the second contact point 23 is offset downward with respect to the first contact point 13 (see FIG. 6B), whereas in the lower terminal 3B, the second contact The point 23 is offset upward with respect to the first contact point 13 (see FIG. 7(b)). As a result, when the upper terminal 3A and the lower terminal 3B are press-fitted into the upper press-fitting hole 33A and the lower press-fitting hole 33B of the housing 2, respectively, the second contact point 23 of the upper terminal 3A and the second contact point 23 of the lower terminal 3B are connected. 23 are located on the same plane (see FIG. 4, etc.). The lower terminal 3B has been described above.

Next, the housing 2 will be explained. The housing 2 is a resin-molded product, and as shown in FIG. 2 and the like, includes a rectangular tubular body portion 31 that extends in the front-rear direction and is long in the left-right direction. The rear end of the body portion 31 is closed by a rectangular plate-shaped rear end wall 32 (see FIGS. 4 and 5), while the front end of the body portion 31 is open. When the connector 1 and the mating connector are mated, the mating connector is inserted and fitted into the inner space of the main body 31 through the front end opening of the main body 31, and the center portion of the upper wall of the main body 31 in the left-right direction. The fitted state is maintained by a lock portion 31a provided in the .

As shown in FIGS. 3(c) and 5, the rear end wall 32 is provided with a plurality of upper press-fit holes 33A aligned in the left-right direction. , a plurality of lower press-fit holes 33B are arranged in the horizontal direction. Each of the upper press-fitting hole 33A and the lower press-fitting hole 33B is a through hole having a rectangular cross section and penetrating in the front-rear direction.

The first terminal portion 11 of the upper terminal 3A is inserted and press-fitted into the upper press-fitting hole 33A from behind. This press-fitting is performed by pressing the first terminal portion 11 forward with a press-fitting jig (not shown) pressed against the pressing surface 16 . This press-fit progresses while rubbing the press-fit projection 14 of the first terminal portion 11 against the inner wall surface of the upper press-fit hole 33A, and the wide portion 15 of the first terminal portion 11 hits the rear edge of the upper press-fit hole 33A. Complete when touched. Similarly, the first terminal portion 11 of the lower terminal 3B is inserted and press-fitted into the lower press-fitting hole 33B from the rear.

As shown in FIG. 4, in the press-fitting completed state, the first contact points 13 of the first terminal portions 11 of the upper terminal 3A and the lower terminal 3B are positioned within the internal space of the body portion 31, and the upper terminal 3A and the lower terminal The second terminal portion 12 of 3B extends rearward from the rear end wall 32 of the body portion 31 , and the second contact portion 23 is exposed to the outside of the body portion 31 . The second contact points 23 of the plurality of upper terminals 3A are arranged side by side in the horizontal direction, and the second contact points 23 of the plurality of lower terminals 3B are arranged side by side in the front side thereof. All the second contact points 23 of the plurality of upper terminals 3A and lower terminals 3B are located on the same plane. The second contact points 23 of the upper terminals 3A are connected to the conductor pattern 42A of the circuit board 4, and the second contact points 23 of the lower terminals 3B are connected to the conductor pattern 42B of the circuit board 4. Become.

The horizontal interval (pitch) between adjacent upper press-fit holes 33A and the horizontal interval (pitch) between adjacent lower press-fit holes 33B are the same. In this example, as can be understood from FIG. 3B, the plurality of upper press-fit holes 33A are arranged to be shifted to the left by half a pitch with respect to the plurality of lower press-fit holes 33B. In other words, the plurality of upper press-fit holes 33A and the plurality of lower press-fit holes 33B are arranged so as not to overlap each other in the vertical direction (so-called zigzag or zigzag) when viewed from the front-rear direction. It is

Therefore, the first terminal portion 11 of the lower terminal 3B1 (see FIGS. 3B and 10) press-fitted into the rightmost lower press-fitting hole 33B among the plurality of lower press-fitting holes 33B has a plurality of upper press-fitting holes 33B. It is positioned on the right side of the first terminal portion 11 of the upper terminal 3A press-fitted into the upper press-fitting hole 33A positioned on the rightmost side of the holes 33A. Conversely, the first terminal portion 11 of the upper terminal 3A1 (see FIGS. 3B and 10) press-fitted into the leftmost upper press-fitting hole 33A among the plurality of upper press-fitting holes 33A is connected to the plurality of lower press-fitting holes 33A. It is positioned on the left side of the first terminal portion 11 of the lower terminal 3B that is press-fitted into the lower press-fitting hole 33B positioned on the leftmost side of the holes 33B. In this example, in order to avoid interference with the locking portion 31a, the upper press-fitting hole 33A is not provided in the central region in the left-right direction (see FIG. 3B). Thereby, the height reduction of the main body portion 31 can be further promoted.

Furthermore, for each of the upper terminal 3A and the lower terminal 3B, the offset amount in the left-right direction between the first terminal portion 11 and the second terminal portion 12 matches the half pitch. For this reason, as shown in FIG. 10, the lower terminal 3B having the first terminal portion 11 press-fitted into the lower press-fitting hole 33B and the upper press-fitting hole 33A positioned to the left of the lower press-fitting hole 33B by the above-mentioned half pitch have With respect to the upper terminal 3A into which the first terminal portion 11 is press-fitted, the position of the second terminal portion 12 of the upper terminal 3A and the position of the first terminal portion 11 of the lower terminal 3B match in the horizontal direction, and The position of the first terminal portion 11 of the upper terminal 3A and the position of the second terminal portion 12 of the lower terminal 3B match.

As shown in FIG. 5 and the like, the rear end wall 32 has a plurality of upper press-fit holes 33A and a plurality of lower press-fit holes 33B which project rearward and laterally between the plurality of upper press-fit holes 33A and the plurality of lower press-fit holes 33B so as to separate them from each other. An extending flat partition wall portion 34 is provided. In this example, the upper surface of the partition wall portion 34 continues flush with the lower edges of the inner walls of the plurality of upper press-fit holes 33A. Thus, by providing the partition wall portion 34, the upper terminal 3A press-fitted into the upper press-fitting hole 33A, the lower terminal 3B press-fitted into the lower press-fitting hole 33B, and the The insulation distance (especially the creepage distance) between can be increased.

Auxiliary wall portions 35 protruding downward are provided on the lower surface of the partition wall portion 34 at positions corresponding to the plurality of lower press-fit holes 33B in the horizontal direction (see FIGS. 5 and 10, etc.). In other words, each auxiliary wall portion 35 is provided between adjacent upper press-fit holes 33A in the left-right direction (see FIG. 10). As a result, the auxiliary wall portion 35 supports the partition wall portion 34, so that even if the thickness of the partition wall portion 34 is reduced, the partition wall portion 34 is prevented from collapsing or the like. Furthermore, since the second terminal portion 12 (particularly, the first portion 19) of each lower terminal 3B is located in the space between the adjacent auxiliary wall portions 35 (see FIG. 10), the insulating distance between the adjacent lower terminals 3B is large. becomes larger. The direction in which the auxiliary wall portion 35 extends (vertical direction) is also referred to as the terminal stage direction.

As shown in FIG. 2 and the like, a pair of projecting portions 36 are provided in the upper regions of the left and right side surfaces of the main body portion 31 so as to project in the left-right direction and extend in the front-rear direction. The pair of projecting portions 36 function as stoppers that define the vertical position of the housing 2 with respect to the circuit board 4 when the housing 2 is mounted on the circuit board 4 . Each protruding portion 36 is provided with a peg attachment portion 37, and a metal peg 6 is attached and fixed to each peg attachment portion 37. As shown in FIG.

A pair of protective wall portions 38 are provided on the main body portion 31 so as to continue from the pair of projecting portions 36 and further protrude rearward. As a result, the pair of protective wall portions 38 are arranged so as to laterally sandwich the second terminal portions 12 of the plurality of upper terminals 3A and lower terminals 3B extending rearward from the plurality of upper press-fit holes 33A and lower press-fit holes 33B. and functions to protect the second terminal portions 12 of the plurality of upper terminals 3A and lower terminals 3B. As shown in FIGS. 2 and 10, a pair of engaging protrusions 39 projecting downward are provided on the lower surfaces of the pair of protective wall portions 38 . The pair of engaging protrusions 39 are to be inserted into the pair of positioning holes 44 (see FIG. 2) of the circuit board 4. As shown in FIG.

As shown in FIG. 10, in this example, the lower terminal 3B1 having the first terminal portion 11 press-fitted into the rightmost lower press-fitting hole 33B among the plurality of upper press-fitting holes 33A and the lower press-fitting holes 33B has a second The terminal portion 12 is located on the left side of the first terminal portion 11 (that is, inside in the left-right direction). Similarly, for the upper terminal 3A1 in which the first terminal portion 11 is press-fitted into the leftmost upper press-fit hole 33A among the plurality of upper press-fit holes 33A and lower press-fit holes 33B, the second terminal portion 12 is the first terminal portion. 11 on the right side (that is, inside in the left-right direction). Therefore, a large gap L1 between the second terminal portion 12 of the lower terminal 3B1 and the right protective wall portion 38 and a large gap L2 between the second terminal portion 12 of the upper terminal 3A1 and the left protective wall portion 38 are secured. becomes easier.

In other words, in both the upper press-fit hole 33A and the lower press-fit hole 33B, the first terminal portion 11 of the terminal 3 is positioned as far outside as possible in the left-right direction, and the second terminal portion 12 of the terminal 3 is positioned between the pair of protective walls. It can be arranged at a position remote from the portion 38 . Therefore, since it is not necessary to design the pair of protective wall portions 38 to escape in the horizontal direction to avoid contact with the second terminal portion 12, the size in the arrangement direction (that is, the horizontal direction) of the housing 2 is can be made smaller. The housing 2 has been described above.

Next, the circuit board 4 will be explained. As shown in FIG. 2, the circuit board 4 made of resin has a rectangular plate-like shape in which rectangular cutouts 41 are formed in regions other than the left and right ends of the front end face. The cutout portion 41 has a shape corresponding to the outer shape of the body portion 31 of the housing 2 (the shape when viewed from above and below).

A plurality of conductor patterns 42A are provided so as to be aligned in the left-right direction on the upper surface of the rear region of the cutout portion 41 of the circuit board 4, corresponding to the second contact points 23 of the plurality of upper terminals 3A. A plurality of conductor patterns 42B are provided in front of the plurality of conductor patterns 42A so as to be aligned in the left-right direction corresponding to the second contact point 23 of the lower terminal 3B.

A pair of recesses 43 are provided on the upper surface of the laterally outer region of the notch 41 of the circuit board 4 so as to correspond to the pair of pegs 6 fixed to the housing 2 . A pair of pegs 6 are accommodated in the pair of recesses 43 and are soldered. A pair of positioning holes (through holes) 44 are provided on the upper surface of the laterally outer region of the plurality of conductor patterns 42A and 42B of the circuit board 4 . The circuit board 4 has been described above.

In order to mount the connector 1 on the circuit board 4, first, the housing 2 is arranged above the circuit board 4, as shown in FIG. Next, the main body portion 31 of the housing 2 is inserted so as to be fitted into the cutout portions 41 of the circuit board 4, the pair of pegs 6 are accommodated in the pair of recesses 43, and the pair of engaging projections 39 are fitted into the pair of positioning holes. 44, the second contact points 23 of the plurality of upper terminals 3A contact the plurality of conductor patterns 42A, respectively, and the second contact points 23 of the plurality of lower terminals 3B contact the plurality of conductor patterns 42B, respectively. , the housing 2 and the circuit board 4 are brought closer to each other in the vertical direction until the lower surfaces of the pair of projecting portions 36 come into contact with the circuit board 4 (see FIG. 1).

Next, the pair of pegs 6 accommodated in the pair of recesses 43 are adhered and fixed to the pair of recesses 43 with an adhesive or solder, and the second contact points 23 of the plurality of upper terminals 3A are connected to the plurality of conductors. The pattern 42A is fixed with solder, and the second contact points 23 of the plurality of lower terminals 3B are fixed with solder to the plurality of conductor patterns 42B. This completes the mounting of the housing 2 on the circuit board 4 . By mounting the connector 1 so as to fit it in the notch 41 provided in the circuit board 4 in this way, the connector 1 and The height of the overall structure of the circuit board 4 can be reduced.

<Action/effect>
As described above, according to the board-mounted connector 1 according to the present embodiment, the press-fit holes 33A and 33B are separated from each other between the plurality of upper press-fit holes 33A and the plurality of lower press-fit holes 33B provided in the housing 2. , there is provided a partition wall portion 34 that protrudes from the housing 2 and extends in the left-right direction (arrangement direction). Therefore, the insulation distance (particularly creepage distance) between the upper terminal 3A and the lower terminal 3B press-fitted into the upper press-fitting hole 33A and the lower press-fitting hole 33B can be increased compared to the case where the partition wall portion 34 is not provided. Furthermore, since the partition wall portion 34 has a shape extending along the left-right direction of the circuit board 4 so as to collectively separate the plurality of upper press-fit holes 33A and the plurality of lower press-fit holes 33B, each upper press-fit hole 33A and the lower press-fit hole 33B Compared to the case where a plurality of independent walls are provided between each of the lower press-fit holes 33B, it is possible to easily form the thin partition walls 34 when forming the housing with a mold or the like. Therefore, the board-mounted connector 1 according to the present embodiment can achieve both miniaturization and low profile of the connector 1 and maintenance of insulation between the plurality of terminals 3A and 3B.

Further, an auxiliary wall portion 35 projecting vertically (in the direction of the terminal row) from the partition wall portion 34 is further provided. Since the auxiliary wall portion 35 supports the partition wall portion 34, even if the thickness of the partition wall portion 34 is reduced, the collapse of the partition wall portion 34 is suppressed. Furthermore, if the auxiliary wall portion 35 is arranged between the adjacent upper press-fit holes 33A, the insulating distance between the upper terminals 3A press-fitted into the upper press-fit holes 33A can be increased. The same applies when the auxiliary wall portion 35 is arranged between the adjacent lower press-fit holes 33B. Therefore, the board-mounted connector 1 according to the present embodiment can further contribute to both reduction in size and height of the connector 1 and maintenance of insulation between the terminals 3A and 3B.

Further, the second terminal portion 12 having the second contact points 23 to be conductively connected to the conductor patterns 42A and 42B of the circuit board 4 has the first contact points 13 to be conductively connected to the mating terminals. The terminal 3 is configured to have a curved portion 17 extending from the first terminal portion 11 and curved around a curved axis along the axis of the first terminal portion 11 . For example, if the terminal 3 has a typical crank shape, after stamping a preform having a first terminal portion 11 and a second terminal portion 12 (see, for example, FIG. 8) from a metal sheet, the first terminal The terminal 3 can be manufactured by performing one bending process so that the portion 11 and the second terminal portion 12 are offset in the thickness direction of the circuit board 4 . That is, it is possible to reduce the number of times the terminal 3 is bent.

Further, the second terminal portion 12 extends from the first terminal portion 11 and extends along the crossing direction via the curved portion 17, and the second terminal portion 18 extends from the end of the standing portion 18 in the direction along the axis. A second point 21 extending from the end of the first point 19 toward a second contact point 23 . As a result, even when the circuit board 4 is arranged at a position offset in the cross direction from the first terminal portion 11, the number of times the terminal 3 is bent during manufacturing is reduced as described above, and the terminal 3 is connected to the circuit. It can be connected to the conductor patterns 42A, 42B of the substrate 4. FIG.

Furthermore, the terminals 3 press-fitted into the housing 2 are connected to the conductor patterns 42A and 42B of the circuit board 4 while the housing 2 of the connector 1 is fitted in the notch 41 of the circuit board 4 . As a result, compared with the case where the connector 1 is placed on the board surface of the circuit board 4, the overall height of the connector-equipped board 7 can be reduced.
